` Application tiled May 22, 1916. Serial No. 99,058.

To all iti/wm t may concern Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in rlCypographical Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States llo. 436,582 to O. Mergenthaler, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold illed with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through distributing mechanism to the magazine from which they started. More particularly, it has reference to inachines wherein the magazine is removable to permit the substitution of another containing matrices of a different face or font.

In some machines, and particularly when the escapeinents are carried by the magazine, it is necessary to disconnect the escapements and their actuating devices before the magazine can be removed, but before this is done, the escapemeiits should be locked against action, as otherwise the disconnection woiild result in the release of the lowermost matrices from the magazine, causing considerable annoyance and inconvenience or even injury to the parts.

One of the objects of my present invention is to avoid this liability, and to that end, specifically I provide means to prevent the disconnection of the actuating devices from the escapements until the latter have first been locked against action. @therebjects and the means employed for carrying them into effect will be specifically pointed out in the detailed description to follow.

In the accompanying drawings,I have shown my invention in preferred form and by way of example and as applied 'to a specific style of machine, but obviously many changes and variations may be made therein and in its mode offapplication without departure from its Spirit. Generally speaking, I desire it to be understood that I do not limit myself to any specific form o r embodiment, except in so far as suoli limitations are specified in the claims.

Referring to the drawings:

Figure l is a side elevation of a portion of a linotype machine, certain parts being broken away, with my invention applied thereto;

Fig. la is a detail-view;

F ig. 2 is a view similar to Fig. 1 with some of the parts in different position;

Fig; 2a is a detail-view;

Fig. 3 illustrates a form similar to that of Figs. l and 2, showing the magazine in full and as occupying a position for removal; and

Fig. 4 is a section on the line t-et of F ig. 2.

Referring to F ig. 3, the matrices are stored in the magazine A and when released therefrom pass into the assembler entrance B, which delivers them to the line assembling ineclianism. When the line is composed, it is transported to the casting devices and thereafter carried upward and delivered to the distributing mechanism C, which separates the matrices according to character and returns them through the channel entrance C1 to the magazine from which they started.

The release of the matrices from the magazine is effected by means of the escapements D, these being of the usual construction and each comprising a rocking lever and a pair of reciprocating pawls which are projected alternately thereby into the magazine at each operation. The escapements are moved in one direction by the springs D1 and in the opposite direction by the connected vertical reeds D2, which are constantly urged and held downward by the stronger springs D3. In the normal position of the parts, the lowermost matrices in the magazine are held against escape by their engagement with the lower pawls of the escapements, which stand projected into the magazine under the influence of the springs D3. IVhen, however, the reeds D2 are raised by thekey controlled mechanism (not shown), the force of the springs D3 is overcome and the weaker springs D1 are allowed to act, which vthen rock the escapements to withdraw the lower pawls to release the lower-most matrices, and simultaneously to project the upper pawls to arrest momentarily the following matrices. Thereafter, the reeds are permitted to descend under the influence of the stronger springs D3, which thus effect the reverse movement of the escapements, withdrawing the upper pawls to allow the'matrices which had been momentarily arrested thereby to slide forwardly, and again projecting the lower pawls to arrest the descending matrices and hold them against escape until the neXt operation. rl`his operation of the escapements is well-known and requires no further description here.

The magazine is supported upon the swinging frame A1, pivotally mounted at its upper end upon the transverse rod A2 (see Fig. 3) and normally resting at its lower end upon the set screws A7. The swinging of the frame A1 is effected by the pair of cams A3 fast to the opposite ends of the transverse rock shaft A journaled in the frame A1, the cams being provided with operating arms A5 and arranged to cooperate with rollers A4 onthe main frame. In eecting the removal of the magazine, therefore, it is merely necessary to turn the arms A5 forwardly from the position shown in Fig. l to that shown in Fig. 3, which action causes the cams to rock the frame A1 upwardly as illustrated in Fig. 3, when the magazine is free to be drawn forwardly from the machine, the arms A5 also giving support to the magazine during such removal. These parts and their mode of operation are also well known and are shown and described in detail in either of the patents to T. S. Homans Nos. S14-.542 and 829,808.

In the present instance, the escapements D are attached to or carried by the magazine A, so that before the magazine is rocked upward in the manner just described, the actuating reeds should first be disconnected from the escapements. For this reason, the guide frame D4, wherein the reeds are slidably located at their upper ends, is arranged to be moved forwardly and backwardly in the machine in order to connect the reeds with or disconnect them from the escapements. These movements of the frame D'L are effected by arms D5 connected thereto and fast upon a transverse rock shaft D, which latter is ournaled in the framework and provided with an operating handle D7.

As before explained, the spring actuated lreeds D2. when connected to the escapements D, hold them in their normal position against the action of the weaker springs D1, which tend constantly to rock the escapements in a direction to release the lowermost matrices. It is evident, therefore, that unless means were otherwise provided, the disconnection of the actuating reeds from the escapements would result in the escape of the lowermost matrices in the magazine, since such disconnection would allow the escapemcnts to be operated by the springs D1. To prevent this liability, the magazine is provided with a rotary grooved rock shaft E, which when turned to diderent positions either permits or prevents the operation of the escapements. Fig. 1n shows the shaft in unlocking position, with its groove above the escapement levers, thus permitting their operation, and Fig. 2a shows it in locking position, with a solid portion in engagement with the escapement levers, thus preventirg their operation. lt is this latter position the rock shaft should occupy before the actuating devices D2 are disconnected from the escapements, and my present invention is directed to means to insure this result.

Referring to Fig. l, the guide frame D4 has connected thereto va pivoted latch F having a grip portion F3 and provided on its under side with a locking piece F1 engaging in front of an upstandirg nose or abutment A on the machine frame. Before the frame can be shifted rearwardly, therefore. the latch F must be raised to disengage its locking piece from the abutment A10. Means are provided to prevent this lifting of the latch until the rock shaft E has been turned to its locking position, such means comprising (see particularly Fig. el) an arm F2 projecting upwardly from the latch F and adapted to cooperate with an enlarged or head portion E2 on one end of the rock shaft, which head portion is recessed or reduced as at E3. The relation of these parts is such that when the rock shaft E is in its unlocking position, as in Figs. l and la, the solid or curved-part of the head portion E2 stands above the arm F2 and thus prevents the lifting of the latch F; and when the shaft is turned to its locking position, as in Figs. 2 and 2, the recess E3 is located above the arm F2, and thus allows the raising of the latch. ln other words, the construction is such that the shifting of the actuating reeds or their disconnection from the escapements cannot be effected until the escapements are first locked against action; or, stated more'specically, the two locking devices for the escapements and the reed shifting-guide, respectively, are so connected or related that the escapement locking device must be moved to' active position before the other can be moved to inactive position. In this way, all danger of the matrices spilling from the magazine lis Obviated.

In order to hold the rock shaft E positively in either itslocking or unlocking position, there is employed a spring detent EG adapted to engage in one or the other of two recesses E5 in the head` portion E2 of the rock shaft. The detent is slidably arranged in a block-A11 secured to the magazine and is provided with an upstanding finger E7 to permit its ready disengagement. The rock shaft is also formed with av pair of stop shoulders E4, which are adapted to engage on opposite sides of the block A11 to limit the movement of the shaft in opposite directions and to secure the proper registration of the recesses A5 with the detent E". The shaft may also be provided if desired with a grip or handle ES to facilitate its turning movements.

Means are also employed to prevent the raising of the magazine for removal until after the escapement reeds have been disconnected from the escapements. means comprise the hook-shaped arm J connected to the rock shaft DG and adapted to engage a stud A9 on one of the cam arms A, when the parts are in their normal position, as shown in Fig. l. In this position, the cam arm is locked and held against rotation, thus preventing the upward movement of the swinging frame A1 and the magazine supported thereby. IVhen, however, the handle D7 is operated to disconnect the reeds from the escapements, the arm J is moved out of engagement with the stud A9, as shown in Fig. 2, and the cam arm may then be manipulated to effect the raising of the magazine, as illustrated in Fig. 3. This specific mechanism is disclosed in my prior Letters Patent No. 1,079,498,but when associated with my present improvements subserves the further function of preventing the removal of the magazine until the escapements have first been locked against action, this result being due to the connection of the arm J with the escapement-reed shifting means, which as before described can only be operated when the escapements have been locked against action.

It is well known that in some machines of the class illustrated, the magazine may be provided with a locking device to engage directly with the contained matrices to hold them therein, instead of engaging with the escapements as shown herein. In both cases, the matrices are locked within the magazine, this result being secured directly in the first case and indirectly in the second. It will be apparent, therefore, that my invention comprehends both arrangements, the essential idea being to insure the locking of the matrices within the magazine before the escapements and their actuating devices are disconnected. However, the use of a locking device to hold the escapements against operation is preferable, possessing certain advantages which would not obtain when it is arranged to cooperate directly with the matrices.

As is also Well known, the locking device may be variously modied in form or ap- These plied to many'diiferent classes of machines. It is to be understood, therefore, that my invention has been shown merely in preferred form and by way of example and as the art and still be comprised within its,
